Set up the evaluation board as needed, according to the previous terms. 2. Connect the evaluation board to a PC with USB cable. USB control is recognized as HID (Human Interface Device) on PC. When it is not recognized properly, please reconnect the evaluation board to PC. 3. Insert the CD-ROM labeled “AKD4712-A Evaluation Kit” into the CD-ROM drive. 4. Access the CD-ROM drive and double-click the icon “akd4712-A.exe” to open the control program. 5. Begin evaluation by following the procedure below. [Supported OS] Windows 2000 / XP 64bit OS is not supported. Windows 95 / 98 / Me / NT are not supported. <KM111300> 2012/06 -5- [AKD4712-A] ■ Operation Screen 1. Start up the control program following the above procedure. 2. After power is supplied to the evaluation board, AK4712 must be reset once by bringing SW2 (AK4712-PDN) from “L” to “H”. 3. The control program operation screen is shown below Figure 2. Control program window ■ Operation Overview Register map and testing are controlled by this control software. These controls may be selected by the upper tabs. Frequently used buttons, such as the register initializing button “Write Default”, are located outside of the switching tab window. Refer to the “■ Dialog Box” section for details of each dialog box setting. ■ Button Functions 1. [Port Reset]: Reset connection to PC Click this button after the control software starts up and the evaluation board is connected to the PC via USB cable. 2. [Write Default]: Register Initialization <KM111300> 2012/06 -6- [AKD4712-A] Use this button to initialize the registers when the device is reset by a hardware reset. 3. [All Write]: Execute write command for all registers displayed. 4. [All Read]: Execute read command for all registers displayed. 5. [Save]: Save current register settings to a file. 6. [Load]: Execute data write from a saved file. 7. [All Reg Write]: [All Reg Write] dialog box pops up. 8. [Data R/W]: [Data R/W] dialog box pops up. 9. [Read]: Read current register settings and display to the Register area (on the right of the main window). This is different from [All Read] button as it does not reflect to the register map. It only displays the current register values in hexadecimal numbers. <KM111300> 2012/06 -7- [AKD4712-A] ■ Tab Functions 1. [REG]: Register Map This tab is for register read and write. Each bit on the register map is a push-button switch. Button Down indicates “H” or “1” and the bit name is shown in red (when read-only the name is shown in dark red). Button Up indicates “L” or “0” and the bit name is shown in blue (when read-only the name is shown in gray) Grayed out registers are Read-Only registers. They can not be controlled. The registers which are not defined on the datasheet are indicated as “---”. Figure 3. [REG] window <KM111300> 2012/06 -8- [AKD4712-A] 1-1. [Write]: Data Write Dialog Select the [Write] button located on the right of the each corresponding address when changing two or more bits on the same address simultaneously. Click the [Write] button for the register pop-up dialog box shown below. When the checkbox next to the register is checked, the data will become “H” or “1”. When the checkbox is not checked, the data will become “L” or “0”. Click [OK] to write the set values to the registers, or click [Cancel] to cancel this setting. Figure 4. [Register Set] window 1-2. [Read]: Data Read Click the [Read] button located on the right of the each corresponding address to execute a register read. The current register value will be displayed in the register window as well as in the upper right hand DEBUG window. Button Down indicates “H” or “1” and the bit name is shown in red (when read only the bit name is shown in dark red). Button Up indicates “L” or “0” and the bit name is shown in blue (when read only the bit name is shown in gray) Please be aware that button statuses will be changed by a Read command. <KM111300> 2012/06 -9- [AKD4712-A] 2.
